Hi,

I am trying to run LabelStudio in a Docker container on a VM in GCP.

The container is listening to a specific port (10xxx).

The URL [https://my.domain.com/labelstudio/](https://my.domain.com/labelstudio/) is routed to the VM and port 10xxx via a GC load balancer.

I have set up the environment variables:

LABEL\_STUDIO\_HOST=”[https://my.domain.com/labelstudio/”](https://my.domain.com/labelstudio/%E2%80%9D)

LABEL\_STUDIO\_PORT=”10xxx”

When starting LabelStudio I see:  
=\> Hostname correctly is set to: [https://my.domain.com/labelstudio/](https://my.domain.com/labelstudio/)  
=\> Django URL prefix is set to: /labelstudio  
=\> Database and media directory: /label-studio/data  
=\> Static URL is set to: /static/

[…]

Starting development server at http://0.0.0.0:10xxx/

The problem starts when I try to access [https://my.domain.com/labelstudio/](https://my.domain.com/labelstudio/)

I get HTTP 404:  
[2025-10-09 11:09:28,117] [django.request::log\_response::253] [WARNING] Not Found: /labelstudio/labelstudio/  
[2025-10-09 11:09:28,121] [django.server::log\_message::213] [WARNING] “GET /labelstudio/ HTTP/1.1” 404 170851

I tried playing with the environment variable LABEL\_STUDIO\_HOST without luck.

Any help would be appreciated.

Many thanks in advance.

Hello,

subdomains are allowed only when you use it together with our nginx configuration:

Many thanks. I got it working without nginx, but with Load Balancer URL rewrite and Docker configurations.
